How early do babies show hand dominance? I've had several people tell me my son looks like he's gonna be a lefty, like me. But, he's 6 months old (3 months adjusted). He's grabbing at his bottle with his left and has been putting his left hand in his mouth the most..

I've been researching a little bit and everything says not until 2 or 3 years old and babies showing preference that early could be a developmental problem. Due to his prematurity that's definitely something I'd be concerned with. My dad said they had a feeling I would be because that's the hand I held my bottle with.

Just wanted to see what you ladies thought.
